Lasing Droplets: Highlighting the Liquid-Air Interface by Laser Emission

摘要

When dye doped ethanol droplets are irradiated with an intense pulsed laser beam, the resulting laser emission from individual droplets highlights the liquid-air interface. Photographs of the lasing droplets in the micrometer size range taken in a single 10 nanosecond laser pulse clearly show the dynamic changes in droplet size, shape, and orientation.
